What is the first thing you should do when approaching a roundabout?

When approaching a roundabout, the first action you should take is to yield to traffic that is already in the roundabout. This is crucial because roundabouts are designed to keep traffic flowing smoothly, and vehicles inside the roundabout have the right of way. Yielding allows you to gauge the traffic conditions and find an appropriate gap to enter safely without disrupting the flow.

In contrast, increasing your speed is not advisable since it can lead to unsafe conditions and increase the risk of collisions as you attempt to enter the roundabout. Looking for a parking space is irrelevant when approaching a roundabout, as it is not a location for parking but for navigating through rotating traffic. Turning on your hazard lights is also inappropriate, as hazard lights should only be used in situations where your vehicle is stationary or poses a hazard to other traffic. Using them while approaching a roundabout can confuse other drivers about your intentions.
